AT2022aedm and a new class of luminous, fast-cooling transients in elliptical galaxies
M. Nicholl, S. Srivastav, M. D. Fulton +49
We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS).…
A Precursor Plateau and Pre-Maximum [O II] Emission in the Superluminous SN2019szu: A Pulsational Pair-Instability Candidate
Aysha Aamer, Matt Nicholl, Anders Jerkstrand +29
We present a detailed study on SN2019szu, a Type I superluminous supernova at , that displayed unique photometric and spectroscopic properties. Pan-STARRS and ZTF forced p…
Broad-emission-line dominated hydrogen-rich luminous supernovae
P. J. Pessi, J. P. Anderson, G. Folatelli +27
Hydrogen-rich Type II supernovae (SNe II) are the most frequently observed class of core-collapse SNe (CCSNe). However, most studies that analyse large samples of SNe II lack event…
A characterization of ASAS-SN core-collapse supernova environments with VLT+MUSE: I. Sample selection, analysis of local environments, and correlations with light curve properties
Thallis Pessi, Jose L. Prieto, Joseph P. Anderson +17
The analysis of core-collapse supernova (CCSN) environments can provide important information on the life cycle of massive stars and constrain the progenitor properties of these po…
SN 2023emq: a flash-ionised Ibn supernova with possible CIII emissio
M. Pursiainen, G. Leloudas, S. Schulze +16
SN 2023emq is a fast-evolving transient initially classified as a rare Type Icn supernova (SN), interacting with a H- and He-free circumstellar medium (CSM) around maximum light. S…
